Electronic structure imperfections and chemical bonding at graphene interfaces
The manifestation of novel phenomena upon scaling to finite size has inspired a paradigm shift in materials science that takes advantage of the distinctive electrical and physical properties of nanomaterials. Remarkably, ...
Fast Energy Relaxation of Hot Carriers Near the Dirac Point of Graphene
We investigate energy relaxation of hot Dirac fermions in monolayer and bilayer graphene devices. Conductance fluctuation thermometry is used to determine the effective carrier temperature at any current, and to compute ...
Probing cyclotron resonant signatures and the AC quantum Hall effect in monolayer and heterogeneous graphene multilayers through mid-infrared, magneto-optical, polarization-sensitive spectroscopy
In 1947 Phillip Wallace introduced the fundamental electronic properties of a single layer of graphite, known as graphene. At that time, graphene was introduced as a theoretical tool that could be used to approximate the ...
Electronic Structure Studies of Graphene and Graphene Oxide Interfaces
Graphene-based research has grown exponentially since the experimental discovery of graphene in 2004 through the mechanical exfoliation of graphite. This synthetic technique realized several fascinating electronic properties ...
